Definitely Has A Use But May Not Be For Everyone

February 8, 2015

I purchased this combination washer/dryer back in December. After having this unit in my house for a little over a month I am so far pleased to say I am happy with my purchase. After purchasing my first home I realized that there was no ventilation ran for a dryer or 220V wiring even ran to where the previous owner had their laundry area setup. This machine solved that issue plus worked well with one of my compulsions about making sure clothes went immediately from the washing machine to the dryer to avoid getting that mildew smell by allowing me to have it automatically start drying after the wash cycle.
As far as the machine’s performance and how it runs. I did some research and read many reviews before making my purchase. One thing that was mentioned over and over through other reviews was the need for the machine to be elevated to help it drain properly. Some people used homemade stands others bought the recommended LG pedestal. Instead of finding out for myself whether or not this machine worked well while sitting flat on the ground I went ahead and purchased the pedestal that goes with it. Something else that was a common mention in other reviews was load size. I experimented with my first few loads to see what worked for me. Since I prefer to wash and dry in my setup I wanted to make sure that I didn’t overfill the machine. It took a few attempts but I found a load size that works well for me, usually a pair of jeans, a few shirts, undergarments, and socks will wash and dry without issue in less than three hours. This works well for my household size of two but if you have a larger household with more laundry and less time this machine may not be ideal for you.
There are a lot of different wash cycles to play with to get your desired results. These may not be for everyone but they are useful and have their functions. Since I generally use a cold wash cycle, extra rinse, and more dry settings I was able to set a custom program so I can just hit a single button to pull up my desired settings each time. Another feature I use a lot is delayed wash. I can load the machine at night and set it to start a couple hours before I generally return home and my clothes will be near done when I return home in the afternoon without setting around getting wrinkly all day.
The only other thing worth mentioning is the lint. There will be some lint remaining in your washer after the cycle is done. You should wipe down the inside of the door and around the rubber seal after each cycle. This doesn’t seem too tedious. There is also a lint trap you should clean once a month. Having performed this task once already I can see that it is easy enough that anyone should be able to do it with the instructions provided. It is worth noting also that I notice that there is a decent amount of lint coming out with the water through the drain hose. I drain into a laundry sink and use a cheap hair catcher to prevent the lint from going down the drain so it hasn’t worried me but it is definitely worth mentioning for those who use another draining method.

fell in love with this machine very quickly

November 11, 2014

I was extremely skeptical of this machine at first, but due to space issues in my condo, decided to try it out. i LOVE It. i haven't had the drying issues that some people mention, it takes about 2 -3 hours to complete a load from start to finish depending on size (which is about the same as my last set), and it dries the clothes completely within that time. my whites are brighter than they have ever been, and i love all the choices for the preset cycles. My favorite feature is the delay start. i set it so that it completes the load just after i wake up, or when i come home from work. Purchased with the pedestal, which makes it the perfect height and adds much needed storage space.

Cleans well, gently on clothes

July 21, 2015

Knowing full well that this machine takes much longer to do a lot has a lot to do with the satisfaction you'll have with this appliance.
My wife and I were intrigued by the machines we used in Europe recently and when our current w/d were wearing out we decided to try one of these combo units using condensing drying.
it does take between 2.5 and 3.5 hours to do most loads. While you can't necessarily have a marathon Saturday where you do all your laundry it's not at all impossible to get several loads done in a day.
Using the delay feature you can load it the night before and have clothes ready by morning followed by several more loads during the day.
A bonus is you can put a load in and leave for several hours to return home to them being done. There's no transferring clothes from one machine to another.
It also doesn't require a special plug or vent as you should already know by now. This can save on heating/cooling bills. Homes these days are being built tighter and tighter and using this machine will allow you not to have a 4 inch hole in the side of your house.
Its water and electricity use is rather low, as well. Over a full cycle it generally uses less than 3 kilowatt hours compared to a conventional washer and dryer that might use upwards of 6-8.
It also doesn't get as hot as a conventional dryer. This has its pluses and minuses. A major plus to me here is that the clothes aren't wearing as fast. Colors are staying longer and the fabric appears/feels less used. And it is true if you've read elsewhere that sometimes the clothes will feel slightly damp when the cycle is complete. If you remove the clothes right as the cycle ends i've found that the dampness leaves rather quickly as the cool. You could also get a small folding drying rack to temporarily hold the clothes while you're folding. In general everything comes out probably 95% dry or so and allowing the clothes to breathe for a minute tends to take the rest of the wetness out of them.

Awesome machine

November 12, 2014

Awesome machine for anyone with a space issue, a disability where bending and changing loads from one machine to another is painful, or you just forget to change the loads and find them wet days later. You put dirty clothes in set wash and dry cycles, add your detergent, push start. Forget about it. When done everything is clean and dry. If only it folded and hung them to. George Jetson must be on the horizon.

Great washer/dryer combo for small home

February 7, 2015

We live in a home without washer/dryer connections and this combo is perfect for us. In my opinion, it is gentler on the clothes and gets them cleaner. I haven't had it very long. But so far so good! :)

Great for a small Family in a apartment.

October 15, 2014

My wife and I were looking for a efficient washer and dryer for a small apartment. We decided with the LG brand since we had positive experience on our previous washer and dryer units. This one is great for small to medium loads because of the steam dry feature. We are not turned off by the unique way of drying clothes, as I have a lot of dress shirts and dress pants that I use on a daily basis. The clothes have come out very damp at first when we started with the unit, now we figured how much is to much. Hook up was easy. We decided to connect to our kitchen sink. We spent about $20 for couplings and additional hoses. It has a powerful motor, having it in a pantry room right is great, cause now the walk in pantry is our laundry room, and the noise is low. This sure beats laundry with neighbors unless that's your thing.

Excellent machine!

September 16, 2015

This washer/dryer is fantastic!!!! It is awesome to put the clothes in dry and return to a completely finished (dry) load. It is especially great for me as I have a disability which makes lifting heavy wet clothing very hard. I LOVE IT! I have NO problems with clothing being damp. Items come out absolutely dry, unless I set the machine to "damp". As far as the machine taking a very long time, it does take longer than regular machines but really not at all bad given that it does both processes. I will NEVER go back and wish I had made the switch years ago!

Perfect for small space, small family / couple.

Bought with 15" LG pedestal for cramped condo laundry closet. My drain in 36" off of floor, have heard that drain height affects drying time/effectiveness. Works without issue 6 months and going, washing and drying.
Washer is same as other LG washers with similar features. Issue for potential buyer is the adjustments needed to get most out of appliance (especially at high price), quirks of drying which are not a barrier for me.
Drying takes longer depending on load size and type of material, and will never get bone dry out of the unit - different drying process.
I use the following steps to wash.
1) Sort clothe for like material. Uneven results with mixed loads.
2) Smaller loads, generally do not go over recommended capacity.
3) Do not have set laundry day. I load at night or before work and let run (with fresh care setting to avoid wrinkles) - and put away later in AM or PM.
4) Wipe lint off of seal of unit.
5) Run unit every two months in clean drum mode.
Works flawlessly for me and lifestyle.

OK so far. But...
Posted by: Marinebiker1700 from: Los Angeles, CA on This has been a pretty good product as of now. It does take quite some time to complete normal wash or dry cycle. I did find one trick though. When doing the laundry start with just a wash cycle (no dry). Then once it finishes you can open the door and put in a softener towel if you wish. Then close the door and select just a drying cycle and choose "no spin" on the spin setting. believe it or not that seems to cut the overall time a little.
So far i'm pleased. and as with any "new tech" item, Just give it time to get used to it and experiment with the cycles.

Best Money I Ever Spent!
Posted by: LauD86 from: on I don't normally write reviews, but after recommending this to everyone I have ever come into contact with, I wasn't satisfied with just telling my inner circle about this. No, I want to tell the world. Because I never had a washer/dryer in my apartments, for years, I sent out my laundry or my mother would do my laundry. I had done laundry maybe once or twice in my entire life. I thought it was an awful chore to go to the laundromat. When my husband and I purchased our first home a few months ago, we had to find a washer/dryer unit that would fit into a closet that was underneath the back of our staircase. We considering stacked units, however, most of the available options were still too big to fit in our laundry closet. We ended up finding one that would fit. Enter the LG Electric Washer/Dryer Combo. At first, I thought it was a bit pricey, and this almost kept us from pulling the trigger. I am the person who will buy the least expensive option of anything available. Upgrades? What's that? I just don't do that - why get the bells and whistles when the basic model does the job? In this case, I was totally wrong. After reading reviews, I was a bit skeptical because many of the reviewers say this baby takes too long to dry. I am SO glad I did not listen. Not only do I do laundry now, but I enjoy doing laundry! There's many different settings - even a hand wash cycle! An entire cycle from start to finish takes about 2 hours (we set our dry time to "more dry", and my clothes always come out toasty warm!) The convenience is worth the extra time it may take. I put in a load at night, and when I wake up in the morning, my clothes are washed and dried. Plus, it takes up way less space than two units, so we were able to put a shelf in our closet to hang over the unit and hold our detergent. The interior is not as small as others may say - it's the perfect size for my husband and I, and we go through a lot of clothes. I will say that I like that it holds less than a separate washing machine, since the loads are smaller it makes the task of putting away the laundry less daunting. The machine itself is so easy that I actually enjoy doing laundry now. DO NOT let the negative reviews hold you back! This thing is seriously the best money I ever spent and a complete time-saver; instead of waiting for the clothes to be washed so I can bend over and put them in the dryer, I can do other things (like sleep!) while I wait for my clothes to wash and dry. I absolutely love my washer/dryer combo unit and will never purchase anything else. Thanks, LG, for making a solid product!
